A recent study of prices revealed that fuel prices around France are at their highest in the Paris region and the island of Corsica. The study also revealed that fuel prices are higher in general in the south and east of the country than the north and the west. Prices are also higher in very rural departments like Cantal, Correze and Tarn simply because there are fewer fuel stations. The government has a very detailed website which lists all the petrol pumps in France and the current fuel prices at each one. You just need to type in where you're going, and you'll get a list of the petrol stations nearby and their prices.
